A defibrillator containing a 18.4 μF capacitor is used to shock the heart of a patient by holding it to the patient's chest. Jus
gregori [183]

Answer:

The energy E is 1603.008 J.

Explanation:

Given that,

Capacitor = 18.4 μF

Voltage = 13.2 kV

We need to calculate the energy

Using formula of energy

E=W=\int{Q}\ dV.....(I)

We know that,

Q=CV

Put the value of Q in equation (I)

E=\int{CV}dV

On integration

E=\dfrac{CV^2}{2}

Put the value into the formula

E=\dfrac{18.4\times10^{-6}\times(13.2\times10^{3})^2}{2}

E=1603.008\ J

Hence, The energy E is 1603.008 J.

If an object has no acceleration, can you conclude that no forces are exerted on it
MrMuchimi

No. It has no acceleration, which just means that the forces acting on it are equal and opposite, not that there are no forces exerted on it.

But if you're talking about the resulting Net Force, then yes you can conclude there is no Net Force acting on an object with no acceleration.

Dear Sir,

           APPRECIATION FOR THE ADMISSION OFFER IN YOUR SCHOOL

          I humbly write this letter to express my sincere appreciation for the offer of admission in your highly esteemed institution of learning. The admission letter states that I was admitted to pursue a programme in Computer Science and this is a source of great delight for me. The opportunity is a unique one because I stand a great chance of acquiring deeper knowledge of programming software that will prove invaluable to me in my future career.  

         Over the years, I have been particularly thrilled with all the inventions that have been made possible with information technology and programming of many useful software. These inventions have made life a lot easier, hence my interest in getting the required knowledge that will enable me to contribute my quota to the society.

         This programme will also afford me the opportunity to relate with seasoned professionals in the field of Information Technology. When in contact with these professionals, I hope to ask them several questions on programming, the technicalities involved in it, and what is obtainable in the real-world scenario. Armed with these pieces of information, I believe that the programme will shape me to be an excellent professional that will be useful to the society.

         Once again, thank you for this very special opportunity. I hope to fully maximize the privilege.

Yours Sincerely,

Jessica Liam.
